WIPER RETURN ERROR

Reason to get defective

The Wiper is the part that comes out and grabs the upper thread at every trim, the Wiper does not cut the thread the only job of the Wiper is to come out and get the thread out of the working area. The Wiper at its function it gets thru the Upper Thread Base set Velcro, it can get bent or damage. Below we can see a Diagram of the Wiper for a Single Head machine and for a Multi head machine.

SOLUTION

We can bend it back to its normal state or replace it if necessary, sometimes is a simple adjustment for the Wiper to get thru the Velcro of the Base Board with no problems, the adjustment is done between the WIPER and the UPPER THREAD BASE SET, the Base set can be adjust it by going up and down to make sure that the Wiper gets through the middle of the Velcro.

When the adjustment is done and if the Wiper is not damage then we have to consider a connection issue, locate the Wiper Motor and trace the cable that plugs to the Joint Board and disconnect the plug and connect it back in. If the connection is fine then we have to consider the Joint Board.

For a newer type Single Head machine E-1501C the Joint Board is located on top of the machine in front of the Thread Rack and for an older style like A or B series the Joint Board is located on the rear right side of the machine, please see pictures below:

E-T1501C E-A and B series machines

For a K series machines the Wiper Motor connects to the BACK PLAIN BOARD LIKE THE PICTURE BELOW

This is behind the CONTROL BOX.

For an older type Embroidery machine like Series A or B the Wiper Motor connects to a Joint Board.

Wiper Issues

The way in which a wiper works, are several parts working together. We will start at the wiper motor and go from there.

The wiper motor sits on the left hand side of your machine and it is either square in shape or bronze domed in shape and color. There is a shaft that sticks out of the right side of the motor, If this shaft has become worn or has the beginnings of rust wither or the exterior or the interior starting to occur then it would not be effective in driving the linkage down. There is also a spring that surrounds the shaft of the wiper motor, If this spring is pitted worn down from the elements or has the rust color to it, then it too would be ineffectual in returning the wiper in the up position.

The next step is the linkage section, it is attached to the wiper motor shaft and is the main arm that extends and retracts the wiper blade, Look at the connective joints of the linkage parts, their are two arms to it, look for any signs of wear from the elements, look especially at the connection point of the two linkages.

Next is the white silicone rectangle block. This white block acts as a guide for the wiper linkage descent and ascent. It is attached to the linkage by a 7mm black hex bolt. Pull the block down and feel how its relationship between it and the guide rail it rides along. Does it stick? or feel rough? If it does then try slightly loosening that hex bolt just a tad so it can extend more properly without sticking on the rail. If the guide rail feels pitted or rough, the remove the hex bolt and the white plastic block, are sure to catch the washer. This is a very important part not to loose. And then with a crocus cloth, polish smooth the outside and inside portion of the guide rail.

The next part you need to inspect is the wiper blade itself. It is important that it does have a slight bow to it, but it is also equally important that their are no other bends into it or dings or dimples of any sort. If you find any of these then replacing the wiper blade would be an excellent choice.

The next step would be the guide that the wiper blade passes through on its way to the Velcro plates. You can locate this metal Guide by looking behind the white plastic bill guide attached to the lower portion of the head. The wiper blade passes through this guide, and this guide is highly susceptible to erosion and damage. Feel around the guides edges where the wiper passes through for and signs of roughness.

Replace this part if it does feel rough, or if it has become damaged during a mishap in the trailed. As you will notice this metal guide is about the same width as the wiper blade, just slightly wider, so you can imagine what kind of problems would occur if it became pitted roughed up or damaged. The wiper would not have a smooth transition in extending and retracting.

The next and final step would be to inspect how the wiper blade is coming into the two Velcro plates. It is important to place your machine on needle 1 first to inspect this. Looking from the right side of the machine so you can eye the tip of the wiper and see the angle at which it penetrates through the two Velcro plates, it is important to ensure that the hooked tip of the wiper is aimed directly into the center of the two Velcro plates. If it favors just slightly the upper plate or lower plate, than as the wiper throws it will receive enough friction from one of those two plates enough to prohibit its full extension and or retraction.

Located on the side of the head are two large Phillip screws, It may be located where the lamp bracket is for newer E series models. Loosening these two screws will allow you to manipulate the two Velcro plates in unison to properly orient it so the wiper is aimed correctly. Again what you do to needle number 1 you must also repeat this on the last needle. I will even do it to the middle needle just to check for a slight bend in my Velcro plate assembly.

While looking down the Velcro plate assembly from either the left or right side, see if you can detect any bends in the Velcro plates. Also look for the Velcro strips as well. Look for signs of the adhesion that holds the strips to the steel plate is coming loose. If so you can easily replace the Velcro strips with new Velcro. If your Velcro plates themselves are bent, than a quick removal and try your skills to re straighten would be recommended. Although be wary that these plates are very malleable and can distort the more you try to reshape them. So often times ordering a new upper thread catcher (Velcro Plate Assy.) would be recommended.

Next, ensure the wiper linkage is intersecting the sensor and not catching on the side of it.

Follow the wiper up until you see the small ā€œUā€ shaped black sensor and see if the linkage is sliding between the ā€œUā€ shaped sensor or if it is hitting the side. Pull the wiper down as illustrated earlier and let it go back see if the squared end of the linkage is positioning correctly between the sensors.
